Fly ash is exported to over 31 countries, with the top 5 countries accounting for over 96% of total fly ash exports from India. Bhutan is the largest importer of fly ash from India, importing $0.92 million worth in 2019-20. The document provides several links to pages on a website that provide further information on fly ash exports, beneficiation processes to reduce carbon content and increase use in concrete, and synthesis of activated carbon from fly ash for hydrogen storage applications.

11. Patented electrostatic separation process
reduces the carbon content of fly ash to
produce a low loss on ignition (LOI) product
used as a partial portland cement replacement
in concrete products.

12. Coal fly ash (CFA) sample with a high unburned carbon content
was used to synthesize ACs. The effect of acid pre-treatment of
the CFA sample using HF and HCl prior to thermochemical
activation using KOH was also investigated. The acid washing
was found to be effective since it removed most of the inorganic
components found in the CFA, as was confirmed by EDS and
XRF. The resulting carbon-rich feedstock had relatively high
content of meso-/macropores as well as with relative increase in
specific surface area (46.19 m2/g - 81.20 m2/g). The obtained AC
sample was found to exhibit high specific surface (946.77 m2/g)
that was dominated by high microporosity and was tested for
hydrogen storage. The H2 uptake (1 bar, 77 K) was found to be
1.35 wt% and with a predictable potential for even higher
capacity when measurements are conducted at high pressures.
